Wirelessly connecting your phone to your Xiaomi Mi Smart TV offers a lot of opportunities, from watching photos on the big screen to streaming 4K videos without HDMI wire. However, many users face problems - the TV does not find the device, the image is lagging or the sound is lost. In this article, we will analyze all the current ways of connecting (including hidden MIUI functions), explain why errors can occur, and give specific solutions for each of them.
Xiaomi TVs have a variety of wireless protocols, from standard Miracast (built into Android) to branded Mi Share, which is faster than its peers, and the connectivity algorithm depends not only on the TV model (e.g. Mi TV 4S vs Mi TV Q2), but also on the firmware version, smartphone operating system, and even router. We tested all methods on current devices (2023-2026) and identified the only universal method that works in 95% of cases — even if the TV does not see the phone in the list of available devices.
1. Preparation of TV and phone for connection
Before connecting devices, you need to follow 4 mandatory steps – skipping them often leads to errors like “Disconnected” or “Device is not supported.” Pay special attention to network settings: the TV and phone must be connected to the same Wi-Fi point (even if you have a Mesh system with multiple nodes).
If you're using a guest network on a router or a feature like Client Isolation, turn it off, they block device interaction on the LAN, and check that the TV is Miracast (some firmwares have it turned off by default).
- 📺 On Xiaomi remote, press Menu → Settings → Connection and sharing → Wireless projection.
- 🔄 Translate Miracast slider to the "On" position (if there is no option, update the TV firmware).
- 🌐 Make sure your TV and phone are connected to the same Wi-Fi network (check the network name in the settings of both devices).
- 🔋 The charge of the phone should be at least 30% – with a low battery level, Android and iOS automatically limit the wireless transmission functions.
⚠️ Note: If you have a Xiaomi TV with firmware older than 2022, Mi Share may not be available. In this case, use Miracast or update the software via Settings → On TV. → Updating the system.
Method 1: Connect via Miracast (for Android)
Miracast is a universal wireless screen standard supported by all Xiaomi TVs and Android smartphones (since version 4.2), and the main advantage of the method is minimal latency (about 50–100 ms), which is critical for gaming or watching videos.
- ❌ It doesn’t work with iPhone (Android only).
- ❌ Requires Wi-Fi Direct support on your phone (check in Wi-Fi settings).
- ❌ Can brake at a weak signal of the router (recommended distance - no more than 5 meters).
Instructions for connection:
- On Xiaomi TV, open Settings → Connection & Sharing → Wireless projection and select Miracast.
- On a smartphone (e.g., Redmi Note 12 or POCO X5), go to Settings → Connections → Screen Transfer (on some MIUI firmware, the path may differ: Settings → Screen → Wireless display).
- In the list of available devices, select the name of your TV (e.g. MiTV-ATV1234).
- Confirm the connection on both devices (entry may be required) PIN-code).

If the TV doesn’t appear on the list, try:
- 🔄 Reboot the router and both devices.
- 📶 Switch to 5GHz in Wi-Fi settings (less interference).
- 🔧 Update the firmware of the TV (relevant for Mi models) TV 4A/4C 2018–2019 garland.).
Method 3: Using Mi Share (branded Xiaomi protocol)
Mi Share is Xiaomi’s proprietary technology that runs faster than Miracast and supports file transfer in the background, but the main difference is that it does not require Wi-Fi Direct, but uses a local network.
- 📱 Smartphones Xiaomi, Redmi, POCO (s MIUI 12 and newer).
- 🍎 iPhone (via the Mi Home app).
- 🖥️ Transfer of photos, videos and music without screen duplication.
How to connect:
- On your TV, turn on Mi Share in the Settings menu → Connection and Sharing → Mi Share.
- On your smartphone, open the Files (or Gallery) app, select the media file and click “Send” → “Mi Share”.
- In the list of devices, select your TV (e.g., MiTV-Q2-55).
- Confirm the reception of the file on TV (notification will appear).
| Parameter | Miracast | Mi Share |
|---|---|---|
| Support for iPhone | ❌ No. | ✅ Yes (via Mi Home) |
| Delay (lag) | 50-100 ms. | 100-200 ms. |
| File transfer | ❌ No. | ✅ Yes. |
| Requires Wi-Fi Direct | ✅ Yes. | ❌ No. |
| It works without the internet. | ✅ Yes. | ✅ Yes. |
⚠️ Note: If artifacts arise when transmitting video via Mi Share (green stripes, jerks), try reducing the file resolution to 1080p or recode it into a format H.264 (for example, through an appendix VLC).
💡
If Mi Share doesn’t find the TV, check if your router is blocking multicast traffic by going to the router control panel (usually at 192.168.1.1) and turning off the “IGMP Snooping” option in the Wi-Fi settings.
4. Method 3: Connecting iPhone to Xiaomi TV (AirPlay)
iPhone or iPad owners can connect to Mi Smart TV via AirPlay, a protocol from Apple that is supported by Xiaomi TVs starting in 2020 (e.g. Mi TV 5, Mi TV Q1).
- ✅ Stable screen transfer without lags (optimized for iOS).
- ✅ Support for Dolby Vision and HDR10+.
- ✅ The ability to stream content from Apple TV+, Netflix and YouTube directly.
Step-by-step:
- On your TV, turn on AirPlay in the Settings menu → Connection and Sharing → Apple AirPlay.
- On your iPhone, swipe down from the top right corner of the screen to open Control Point.
- Click on the Screen Duplication (or Screen Mirroring) icon.
If the connection fails:
- 🔄 Make sure your TV is on Network Sharing (Settings) → System system → General).
- 🛠️ Update your TV firmware to the latest version (older versions of AirPlay are unstable).
- 🔒 Turn it off. VPN iPhone – It can block local traffic.
What if AirPlay is connected but there is no sound?
5. Method 4: Transfer content over DLNA (for video and music)
DLNA is a protocol for streaming media over a local network, which does not duplicate screens, but only transmits videos, music or photos, and works even on older Xiaomi Mi TV models (such as Mi TV 3S).
The connection will require:
- 📱 On the phone – any application with support DLNA (for example, VLC, BubbleUPnP or LocalCast).
- 📺 On the TV, it's on. DLNA-server (Settings) → Connection and sharing → DLNA).
Instructions:
- Install the VLC app on your phone (available for Android and iOS).
- Open the video or music in VLC, click on the transmission icon (📤) and select "Play on the device»**.
- In the list, find your Xiaomi TV (e.g., MiTV-DLNA-55).
- Confirm the playback on TV.
If the TV is not on the list DLNA-device:
- 🔧 Check that UPnP is enabled on the router (in local network settings).
- 🔄 Restart the TV and smartphone.
- 📡 Try connecting via 5GHz Wi-Fi – it’s less busy than 2.4GHz.
💡
DLNA is the only way to transfer MKV or FLAC video without converting, Miracast and AirPlay do not support such files.
6. Solving common problems
Even if set up properly, the connection may not work due to hardware or software limitations, and below is a list of bugs and solutions collected based on Xiaomi support calls.
| Problem. | Possible cause | Decision |

- Use Google Cast (for Android) or Apple TV (for iOS) through apps like YouTube or Netflix (transfer icon) 📤 pop up).
- Update the TV firmware manually by downloading the file from the official Xiaomi website.
7. Comparison of methods: which one to choose?
The choice of connection method depends on your task:
- 🎮 For games: Miracast (minimum delays).
- 🎬 For the movies in 4K: AirPlay (for iPhone) or DLNA (Android).
- 📷 Photos: Mi Share (quickly and without compression).
- 🔄 For screen duplication: Miracast (Android) or AirPlay (iOS).
If you need a stable connection without breaks, use 5GHz Wi-Fi and turn off functions on the router like Band Steering (they can force devices to switch between frequencies). For maximum video quality, set up the Game mode on the TV (Settings → Picture → Image Mode) - it reduces signal processing delays.
💡
On Xiaomi TVs with the Amlogic T972 chip (models 2021-2023), Miracast works more stable than on older MStar chips. Check the processor model in the Settings menu → About TV → Hardware information.
